Here is some more info Paddu, sorry for the delay.

As said before, I use 2 VM for testing. On VM named f18a runs a simulation 
program named qbg22sim. It is in the git repository, together with its man
On the other VM named f18b, runs lldpad and vdptest. vdptest sends a VSI
created command via netlink to lldpad. lldpad then sends this commands
to the switch. Right now lldpad stops at function vdp22_request. That is the
end of my work right now. We have to start from here for station support.

Bridge support on the other hand is independent user input to create/delete
VSI profiles, but requires a working counterpart. I wanted to use lldpad
for this.
I can send you an input file for the qbg22sim to establish evb parameters
and an lldpad configuration file to request reflectivce-relay.

May I ask what are your plans with IEEE802.1 Qbg protocol?
